Happy holidays, everyone! The year may be winding down, but the Spring ecosystem continues unabated. We’re now a few weeks past the generational Spring Boot 4.0 release in November, and there have been tons of releases (and patches) since then. There’s also equal excitement reflected in posts from the community, so we’ve got a lot to dig into this week. So, without further ado…

Hi, Spring fans! I'm so excited to chat with fellow Spring developer advocate Dan Vega about his new book, Fundamentals of Software Engineering

Hi, Spring fans! Welcome to another installment of This Week in Spring. By mistake, I inadvertently published older content in this installment, then tried to fix it and ended up re-publishing the same content. And, what's worse, I somehow ended up deleting the draft I had written for this installment — the one I intended to copy in to override the bad content. Ugh. A comedy of errors. Anyway, this is a lesson in why you should make sure you get enough sleep. And this is why I am now re-writing the same content again!

So, without any further ado, here finally is this week's roundup!

• this is an exciting look at the next generation of the Spring Tools projects

Hi, Spring fans! Welcome to another illustrious installment of This Week in Spring! It’s Thanksgiving week here in the United States. Thanksgiving is traditionally celebrated with friends and family every fourth Thursday of November, gathered around a table full of food and, usually, a giant stuffed turkey. When celebrated well, it’s a time to come together and revel in gratitude for life’s good fortunes. And so, in that spirit, my friends, I want to remind you — and I’m sure I can speak for the entire Spring team here, too! — that we are so grateful for you. The community is the most amazing…
